Developing Anticoagulation Self-Report Measure in Adults

Patients who agree to participate will access a web-based survey (SurveyMonkey) via social media, mobile messages, or emails. The invitation will provide study details, eligibility criteria, and tasks. Patients will confirm inclusion/exclusion criteria upon access, and those ineligible will opt out. Data collection will take approximately 10 minutes per patient. Collected data will be sent to an electronic data collector and saved as an eCRF file in REDCap. The study will conduct two cross-sectional data collection rounds using web surveys to ensure anonymity. Convenience sampling will target anticoagulated patient associations' webpages and social media (e.g., Feder-AIPA, AICCA). In the second round, participants will be informed not to resubmit if they have already completed the survey to avoid overlapping responses.
